Palantir

a multichannel interactive streaming solution

Online Demos

We are looking for new, interesting demo locations. If you have a running
Palantir installation and would like to be added to this list, please
contact us.

It is possible to connect freely to some Palantir installations on the Internet.

These systems can be accessed in a variety of ways:

Take a snapshot from the video camera (with any browser).

Watch the live stream in a supported browser (currently Netscape and Mozilla on
all operating systems, and Internet Explorer on the Macintosh only).

Check the status of the devices connected to the server.

Download the Windows client and start it (no installation is required) to watch
the video stream with minimum latency, listen to the audio channel, and check
and operate the devices connected to the server.
Note that the client is server-independent, so it is only necessary to download
it once. Just change the URL in the server address text box, or select another
server from the "Servers" menu.
A brief introduction to the Windows client is available
here.

The Palantir software runs on the main radio station server, a 233 MHz Pentium
with 128 MB of RAM. The video device is a PCI capture card fed by two
different sources: a composite color camera aimed at the station's
equipment racks, and the current broadcast from the ATV relay.

The connection time is limited to 90 seconds.
Only 4 simultaneous streaming clients are allowed; clients in excess get a
snapshot.

Available devices

Clients can check and set the following server parameters:

the video source to capture from:

channel 0: the signal relayed by the local ATV repeater;

channel 1: the camera inside the museum;

the brightness level for captured frames (adjustable by clients);

the system CPU load average for the last minute (normalized to unity);

the number of running processes;

the amount of used RAM in the system, in megabytes.

This server is located north of Salt Lake City and streams a beautiful view of
the Great Salt Lake (if the sky is clean it is possible to see Antelope Island
in the middle of it).
The camera, along with some weather
instrumentation, is operated by Matt Pope.

This machine, located in Milan, Italy, features an Athlon 64 3000+
running a 2.6.21.3 Linux kernel.

The server is connected to the Internet through an ADSL link with an
outgoing bandwidth of 1 Mbit/s.

The recommended time for connecting is between 10:00 AM and 01:00 AM (timezone
GMT +2). Outside this interval the machine might be down, but you are welcome to
check anyway.

The server captures video from the TV tuner embedded in a Bt8x8 grabber
card. The connection time is limited to 120 seconds.
The monitorable devices exposed by this server are mostly "virtual",
i. e. a reflection of some internal system parameters fed into the server by the
sysfeed daemon (included in the distribution).
These are:

the brightness level for captured frames (adjustable by clients);

the system CPU load average for the last minute (normalized to unity);
